Reviewer score 94% (normalized by Neofiliac)

Reviewers from pcmag have found:

The Hisense U8G series gets much brighter at 1,763.368cd/m^2 with an HDR signal and an 18% white field. The 55R646 is a 120Hz TV that supports variable refresh rate (VRR) and auto low latency mode (ALLM), which should please gamers. The TCL 4K Google TV 6-Series is a fantastic TV line that offers more features and slightly improved performance.

Pros

Excellent SDR and HDR performance
Excellent contrast and color accuracy
Hands-free Google Assistant

Cons

Doesn’t support AMD FreeSync or Nvidia G-Sync

Reviewers from rtings have found:

The TCL 6 Series/R646 is great for most uses. It's impressive for watching movies because it displays deep blacks, and it has a decent Mini LED local dimming feature, but it doesn't improve the picture quality that much. Gamers should appreciate the VRR support, HDMI 2.1 inputs, and low input lag. It displays a wide color gamut and gets bright enough to make highlights pop.

Pros

Outstanding contrast ratio
Excellent reflection handling
Decent local dimming
Low input lag

Cons

Narrow viewing angles
Doesn't improve the picture quality in dark scenes
